Rust, with Mozilla backing it, is probably not going to get you sued. Nim has potential given their commercial interests are paid development and support so far. As in, less greedy they are the better. Languages with community-focused foundations, such as Python, controlling them are probably pretty safe. Although it was risky, the D language now has a foundation. Although no foundation or legal protections, the Myrddin and Zig languages are being run by folks that look helpful rather than predatory.
So, there's you a few examples you might consider if avoiding dependencies on companies likely to pull shit in the future. Venture-backed, publicly-traded, growth-at-all-costs, and/or profit-maximizing-at-all-costs are examples of what to avoid if wanting to future-proof against evil managers turning it from good dependency into bad one.
